Question

Trying to write a code at the moment that basically tests to see if the letter that lies at r (so here (2,3)) is equal to a particular letter or string.

def test():

txt = "test.txt"
r = (2,3)
if txt[r[0]][r[1]] == 'l':
    return (True)
elif txt[r[0]][c[1]] == "m":
    return (False)
elif txt[r[0]][c[1]] == "b":
    return (True)

But i keep getting an error. The error dialogue is this:

if txt[r[0]][r[1]] == 'l':
IndexError: string index out of range

I have no idea what im doing wrong considering i had it working earlier today.
Also, before you ask, i have to code it this way for a particular reason.

Thanks.

Please note,

if txt[r[0]][r[1]] == 'l':

should be written as

if txt[r[0]:r[1]] == 'l':

and similarly other usage should be changed
